install gui with old icons

[alexZZ]

Greetings
encountered an unexpected inconvenience.
all the time we used a standard openvpn gui
But in the latest version of the program icons have changed, which is not very convenient.
As used in the work program with very similar icons.
Tell me how to revert to the old icons, or put their own, including the tray?

I want to express a request to the authors, developers of the program-GUI, in future versions provide a choice of icons.
